An organization manages a large cloud-deployed application that employs a microservices architecture. No notable issues occur with downtime because the services of this application are redundantly deployed over three or more data center regions. However, several times a week reports are received about application slowness. The container orchestration logs show faults in a variety of containers that cause them to fail and then spin up brand new. Which action must be taken to improve the resiliency design of the application while maintaining current scale?
Select the answer
1 correct answer
A.
Update the base image of the containers.
B.
Test the execution of the application with another cloud services platform.
C.
Increase the number of containers running per service.
D.
Add consistent “try/catch(exception)” clauses to the code.

How should a web application be designed to work on a platform where up to 1000 requests per second can be served?
Select the answer
1 correct answer
A.
Use algorithms like random early detection to deny excessive requests.
B.
Set a per-user limit (for example, 5 requests/minute/user) and deny the requests from the users who have reached the limit.
C.
Only 1000 user connections are allowed; further connections are denied so that all connected users can be served.

A network operations team is using the cloud to automate some of their managed customer and branch locations. They require that all of their tooling be ephemeral by design and that the entire automation environment can be recreated without manual commands. Automation code and configuration state will be stored in git for change control and versioning. The engineering high-level plan is to use VMs in a cloud- provider environment then configure open source tooling onto these VMs to poll, test, and configure the remote devices, as well as deploy the tooling itself. Which configuration management and/or automation tooling is needed for this solution?
Select the answer

A.
Ansible
B.
Ansible and Terraform
